* No longer publicly expose the `PeripheralClockControl` struct * Update examples as needed to get things building again * Update CHANGELOG.md * Address review feedback, fix a warning * Use a critical section for all devices other than the ESP32-C6/H2, as they modify multiple registers * Rebase and update `etm` driver to fix build errors
